SPOOL FOR TREATING YARN OR ROVE WITH LIQUIDS Filed Oct. 24, 1928 2 Sheets-Sheet 2 A T TOR/V! Y Patented Mar. 10, 1931 UNITED STATES PATENT OFFICE HENRY COWAN WATSON AND MARTIN WADDELL, OF BELFAST, IRELAND, ASSIGNORS TO WATSON-WADDELL LIMITED, OF BELFAST, IRELAND SPOOL FOR TREATING YARN 0R, ROVE WITH LIQUIDS Application filed October 24, 1928, Serial No. 314,594, and in Great Britain November 25, 1927.

The retting, boiling or bleaching of twisted fibres in the form of rove or yarn has not hitherto been found practicable even on perforated bobbins as air ockets are formed between the barrel and cad of the bobbin on which the rove and yarn is wound and the outer layers of rove or yarn coming into contact with the liquid form a more or less air tight covering through which the liquid will not penetrate to the inner layers or will only penetrate unevenly so that the inner layers are only treated unevenly.

We have found that the rove or yarn of unretted flax fibre can be treated with liquor if wound on an open bobbin or reel having the barrel so constructed as to provide cavities open to the internal centre which will permit free access of the liquor to the inner layers of rove wound thereon.

The bobbin or reel may be formed of wires with an open head or corrugated with longitudinal grooves extending along the barrel so that the bottom layer of yarn or rove is open to the liquid the head of the barrel be ing open or perforated at each end the perforations entering at the ends of the grooves or between the wires.

According to the invention the reel or bobbin is constructed as herewith described and shown in the accompanying drawings.

Fig. 1 is an elevation of open reel or bobbin made of wire.

Fig. 2 is a sectional plan.

Fig. 3 is an elevation of support in position.

Fig. 4 is an elevation of the creel support.

Figs. 5 and 6 are elevations of bobbin showing another form of the invention.

Referring to'Figs. 1 to 4 the reel or bobbin is made of longitudinal wires A to form a barrel bent at the ends around wire rings B to form a head the reel or bobbin being completely open in the centre like a wire cage. The Wires A and B may be galvanized or of rustless iron or steel which will resist the action of acids or alkalies. In winding the rove or yarn the bobbin illustrated may be placed upon the ordinary wood bobbin of a roving frame and removed therefrom. A creel support D of wire shown in Fig. 4 may same with creel be fitted inside the open creel or bobbin when removed from the winding frame to support it in a creel to unwind the rove therefromor it may be mounted upon a wooden or other support.

Referring to Figs. 5 and 6 the reel or bobbin is made with a longitudinally grooved or corrugated barrel E fitted to annular heads F. The heads are perforated with holes f at intervals between the corrugations of the barrel to allow the free flow. of liquor to the interior of the rove. The barrel may be made of wood or metal (galvanized or otherwise) and the valleys of the corrugation may be perforated or slots may be cut therein to allow of the flow of liquor from the interior of the bobbin to the rove wound thereon. Radial slots or grooves may also be made on the interior of the bobbin heads leading to the perforations therein or to the grooves in the barrel.

By the use of such bobbin, flax yarn or rove can be retted and/or boiled, scoured, soured or treated with bleaching liquids after it has been twisted and without winding it from one bobbin to another.

What we claim as our invention and desire to protect by Letters Patent is 1. An open reel or bobbin on which to Wind flax yarn or rove and treat it with liq uor without rewinding, comprising a plurality of longitudinal rods, a circular Wire ring at each end, the longitudinal rods being angularly spaced to form a barrel of smaller diameter than the wire ring and bent outwards at their ends and connected thereto to provide a flange, and a wire support bent to form a spiral at each end to enter and contact with the barrel.

2. An open reel or bobbin on which to wind flax yarn or rove and treat it with liquor without rewinding, comprising a plurality of longitudinal rods, a circular wire ring at each end, the longitudinal rods being angularly spaced to form a barrel of smaller diameter than the wire ring bent outwards at their ends and connected thereto to provide a flange, and a wire support bent to form a spiral at each end to enter and contact with the barrel, the spiral at one end being greater in diameter than that at the other end.

In testimony whereof We have hereunto 5 set our hands this 29th day of September,

HENRY COYVAN VATSON. MARTIN VADDELL.
